Contrast sensitivity functions in autoencoders
Journal of Vision, 2022 Three decades ago, Atick et al. suggested that human frequency sensitivity may emerge from the enhancement required for a more efficient analysis of retinal images. Here we reassess the relevance of low-level vision tasks in the explanation of the Contrast Sensitivity Functions (CSFs) in light of (1) the current trend of using artificial neural ...

Octopaminergic modulation of contrast sensitivity
Frontiers in Integrative Neuroscience, 2012 Sensory systems adapt to prolonged stimulation by decreasing their response to prevailing stimulus conditions. Whereas visual motion adaptation has traditionally been studied in immobilized animals, recent work indicates that the animal’s behavioral ...

A `bright zone' in male hoverfly (Eristalis tenax) eyes and associated faster motion detection and increased contrast sensitivity [PDF]
, 2006 Eyes of the hoverfly Eristalis tenax are sexually dimorphic such that males have a fronto-dorsal region of large facets. In contrast to other large flies in which large facets are associated with a decreased interommatidial angle to form a dorsal `acute ...
